Hi,

I'm working on the Mesa project's build system using autoconf, automake, and
libtool. We're running into the following problem:

We use the formula
 version-info = Major+minor:Mesa_version:Minor
to compute proper libtool version-info from the OpenGL version number (1.2)
and our current Mesa release number (MM.Mm.Mt, e.g. 3.5.0). So, Mesa_version
is an integer derived from that release number. We'd like to use
 Mesa_version = MM * 10^4 + Mm * 10^2 + Mt
which would yield something like 30500. However libtool only accepts three
digits for the REVISION part of the version-info (as Marcelo mentions below).
Is it possible to extend that limitation to five or six digits?

That would be greatly appreciated.
Thanks in advance,

Sven

PS: Libtool rocks!

 because libtool defines non negative as:

    0 | [1-9] | [1-9][0-9] | [1-9][0-9][0-9]

 i.e., it not only can't start with 0, it can only have three digits.  I
 suspect this has to do with some funny test or expr implementation.  Or
 perhaps they thought three digits would be enough.  Or maybe some sick
 linker uses integers to store this info.
 
 Hmm... funky that '0 | [1-9]' bit...
